'Evil One' in the Bible

I am writing to you, fathers, because you know Him who has existed from the very beginning. I am writing to you, young men, because you have overcome the Evil one. I have written to you, children, because you know the Father.

I have written to you, fathers, because you know Him who has existed from the very beginning. I have written to you, young men, because you are strong and God's Message still has a place in your hearts, and you have overcome the Evil one.

We are not to resemble Cain, who was a child of the Evil one and killed his own brother. And why did he kill him? Because his own actions were wicked and his brother's actions righteous.

We know that no one who is a child of God lives in sin, but He who is God's Child keeps him, and the Evil one cannot touch him.

We know that we are children of God, and that the whole world lies in the power of the Evil one.
